Toughened Glass Insulators

MacLean Power Systems offers advanced Modular Designed Toughened Glass that covers voltage classes from 15 to 1150kV applications.  Our premium glass insulators enable our customers to cover all their system voltages while taking up less inventory space than polymer insulators.

Precise Construction

Toughened Glass provides a very long service life compared to other insulation materials.  In product life tests our product routinely holds upwards of 95% of specified Mechanical & Electrical ratings.  This performance is driven by a number of factors:

Durable Materials

  • Our insulators consist of very few metal fittings that could corrode in harsh environments.
  • The glass insulation material does not age over time

Optimized Composition

  • Zinc sleeves on all glass disks provide an extra layer of protection and mitigates pin corrosion
  • RTV Silicone Coating is available for areas with high contamination
  • Additional TransArmour coating is available on galvanized metal fittings

Quality Manufacturing

  • Caps are manufactured with a smooth, uniform galvanizing finish
  • Alumina cement is feathered evenly to ensure that the gap between the cap and the shell is filled, which delivers higher RIV performance vs. felt rings or flocking material systems.  
  • ANSI standards (C29.2B) place limit of  50µV RIV at 1000 kHz with an applied 10kV voltage and we consistently test below 10µV.

Features & Advantages

From the factory to the field our toughened glass modular system provides dependable high performance, low inventory requirements, easy inspection and maintenance vs. other systems saving our customers valuable time and dollars. 

To ensure this we go beyond industry standards with extensive quality control and clear transparency on country of origin on all materials.

Advanced Quality Assurance

100% of our insulators are subjected to a 10kV power frequency voltage prior to packing. 

This means every insulator delivered to our customer has been electrically and mechanically proofed before delivery vs. other manufacturers who test a very small percentage of product.

American Stocked – European Sourced

Every insulator is clearly identified where it is manufactured and assembled. 

Visual competent inspection

The properties of our toughened glass shells provide a clear visual indication of any damage and the need for necessary replacement with simple observation from the ground.

Inventory Reduction

Minimize number of SKUs to stock: Simply add or replace individual glass insulators to a series to expand voltage protection. Individual disks can be connected in series to cover voltages from 15 to 1150kV.

From the factory to the field, our toughened glass modular system provides dependable high performance, low inventory requirements, easy inspection and maintenance vs. other systems saving our customers valuable time and dollars. To ensure this we go beyond industry standards with extensive quality control and clear transparency on country of origin on all materials.
